Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Smart watch Timex Ironman R300 GPS 27.02.2020

The American brand Timex introduced the Ironman R300 GPS smart watch, which offers essential training, heart rate monitoring, tips from top athletes and coaches, a range of daily activity metrics, call and message notifications, the ability to dive in water up to 30 m and good autonomy. At the same time, the cost of the Ironman R300 is only $120.

Like the Timex Ironman One GPS, it's more of a fitness band than a smartwatch, but the company is positioning it as a "smartwatch for sports." Potential Ironman R300 owners are users who want a reliable fitness tracker without unnecessary features, but with a long battery life. The manufacturer claims that the autonomy of the gadget is up to 25 days with GPS turned off. If it is enabled, the operating time is reduced to 20 hours.

The rest of the features are what you would expect from a device like this. Here you can change the watch face, scroll through the screens and view training data. The watch comes with a silicone strap in grey, black and silver color options.
